Ok,me no expert here myself,however i have just been using a package called Reaper on trial after a top DJ on here told me to try it.
You can stretch vocals using ALT.Unfortunetly although this gives me some understanding of stretching due to be able to press F2 and change a setting there,its not against the BPM,which is obviously the dogs bollox.If you can go ah,my BPM is 152,this is???,please work!

,then that would be great,but you can't on Reaper i'm afraid so...
I have WavePad for vocals and can't find nothing in there for it either,so i emailed them.They told me you can do BPM timestretching in a package called MIXPAD which they provide.Might be worth checking that out mate on a trial or something.I'm going to try and get it,when i've finished my new one,as i've no idea if vocals are in time apart from on hearing other works and feel.

I also believe you can do it in FL STUDIO using some plugin,someone at facebook told me.
